Definitions

  • the present invention relates to the field of sensors and in particular to a method for identifying said sensors making it possible to differentiate them and to locate them, as well as a device for implementing said method.
  • the present invention advantageously applies to pressure sensors housed in tires of a motor vehicle, sensors generally associated with a computer of a motor vehicle to which said sensors transmit data.
  • the sensor/onboard computer assembly is thus designated by the term electronic “tire pressure monitoring system” (with the associated abbreviation “TPMS”).
  • Each pressure sensor is conventionally equipped with a radio-frequency transmitter for transmitting data to the onboard computer.
  • the onboard computer receiving the data from the sensors can thus alert the user of the vehicle if one of the tires were to burst or deflate, causing a risk for their safety.
  • the pressure sensor housed in the wheel is ordinarily not removable, and thus changing a wheel involves changing the sensor, and the new sensor is then no longer detected by the onboard computer of the vehicle.
  • TPMS tool a dedicated learning device
  • said device being configured for activating the sensors, recovering and recording the relevant data transmitted by the sensor, such as the identifier of the sensor, and transmitting them to the onboard computer, so that the latter detects and locates the sensors housed in the newly installed tires and can pick up the signals therefrom, in order to warn the user in the event of a pressure drop in one of said tires.
  • the wheels are mounted in pairs at each end of the axles, and it is then said that the wheels are twinned.
  • the sensors are sequentially activated in a predetermined order so that the onboard computer identifies and associates the sensors with each of the wheels of the vehicle.
  • a simultaneous activation of several sensors may be done unintentionally when they are interrogated by the operator by means of his sensor activation device (such as the learning device). The operator can then not determine whether there is activation of the sensor housed in the outer wheel or activation of the sensor housed in the inner wheel.
  • the invention is thus a novel method for identifying pressure sensors, in particular pressure sensors for an electronic tire pressure monitoring system of a motor vehicle, said sensors comprising at least one module for emitting and receiving data,
  • the method according to the invention makes it possible to identify or distinguish the sensors housed in twinned wheels or in environments including a plurality of sensors, this has the advantage of being simple to implement while being applicable in a great diversity of situations.
  • the signal activating the sensors is transmitted at constant power.
  • each of the signals is characterised by a value indicative of the adaptation undergone by each of the signals following its attenuation and its amplification, the value indicative of the power of the signal being the adaptation value of said signal.
  • FIG. 2 is an enlarged view of the device of FIG. 1 ;
  • the device 1 comprises a case 13 , for example made from plastics material, a display device 15 , a keypad 17 and an antenna 19 for transmitting a sensor activation signal, as well as an OBD (designating in English “onboard diagnostic”) socket.
  • Said OBD socket 21 is configured for enabling for example the device 1 to be connected to the onboard computer 11 of a vehicle, in particular by means of an OBD cable.
  • said device 1 transmits an activation signal, for example in the direction of the sensors C 1 and C 2 housed in twinned wheels 7 a and 7 b of the lorry 6 .
  • the amplifier 33 c is configured for amplifying the input signals to a certain amplitude (or power) level, the amplifier 33 c will therefore automatically amplify the signals so that they have the same output amplitude and/or power.
  • the output characteristics of said signals depend in particular on the electronic components (sensor etc.) downstream of the amplifier 33 c and on their configuration (i.e. which characteristics the signals must have to be processed by said electronic components).
  • the signals transmitted by the sensors C 1 and C 2 are attenuated identically and amplified at a fixed level (for example to obtain a given signal to noise ratio).
  • Each of the amplified signals can therefore be characterised by a gain G that is proportional to the power of the signal received and the attenuation applied by the attenuator 33 b .
  • the value of the gain G is therefore a value representing the power of the signal.
  • the value representing the power of the signal is the value of the gain applied to the signal, but this may be other characteristic quantities or a function dependent on several parameters (such as the attenuation, the gain, etc.).
  • the electronic entity 35 is configured for managing the duration of reception in order to receive a plurality of signals coming from the same sensors 9 .
  • each signal transmitted by a sensor 9 comprises an identifier particular to the sensor
  • the electronic entity 35 can classify the received signals on the basis of their origin (i.e. from the sensor that transmitted said signal). Receiving a plurality of signals for the same sensor can for example make it possible to select the signal having the greatest gain value G (or a value indicative of power) in order next to proceed with a comparison and the identification of the relative spatial positions between two sensors.
  • the electronic entity 35 compares in pairs the value indicative of the power of the received signals, and makes it possible to check that the value indicative of the power of the signals transmitted by a sensor 9 is always less than or greater than the signals transmitted by other sensors 9 . If this is the case there is identification of the relative spatial position of at least one of the sensors 9 that transmitted a signal.
  • This supplementary operation increases the chances of correctly identifying the spatial position of a sensor 9 .
